Relationship between atopic dermatitis, depression and anxiety: a two-sample Mendelian randomization study.

BACKGROUND: Growing evidence suggests that atopic dermatitis (AD) is associated with an increased risk of depressive disorders and anxiety. However, existing studies were observational and may have uncovered correlations but could not easily disentangle noncausal or reverse-causal associations because these associations could be confounded and may not reflect true causal relationships. OBJECTIVES: To examine, in a two-sample Mendelian randomization study, the potential effect of AD on the risk of depressive disorders and anxiety. METHODS: Genetic instruments from the largest available genome-wide association study (GWAS) for AD (10 788 cases and 30 047 controls) were used to investigate the relationship to broad depression (170 756 cases and 329 443 controls), major depressive disorder (MDD; 30 603 cases and 143 916 controls) and anxiety (5580 cases and 11 730 controls). A set of complementary approaches were carried out to assess horizontal pleiotropy and related potential caveats occurring in MR studies. RESULTS: We observed no causal impact of AD on the risk of depressive disorders and anxiety, with close-to-zero effect estimates. The inverse weighted method revealed no associations of AD on broad depression [odds ratio (OR) 1·014; P = 0·431], probable MDD (OR 1·002; P = 0·568), International Classification of Diseases, Ninth/Tenth Revision-based MDD (OR 1·001; P = 0·466) or anxiety (OR 1·097; P = 0·180). CONCLUSIONS: This MR study does not support a causal effect of AD on depression and anxiety.

Suicidality and risk of suicidality in psoriasis: a critical appraisal of two systematic reviews and meta-analyses.

AIM: Chi et al.1 and Singh et al.2 each conducted a systematic review and meta-analysis of observational studies examining the relationship between suicidality and psoriasis. SETTING AND DESIGN: Chi et al. included only cohort studies while Singh et al. included cohort, cross-sectional and case-control studies. PRIMARY EXPOSURE AND OUTCOME: The primary outcome, suicidality, was assessed in people with psoriasis (exposure) and people without psoriasis. Analyses were separated for suicidal ideation and behaviour. RESULTS: Chi et al. included five population-based cohort studies that were considered to be of high quality according to the Newcastle-Ottawa Scale (NOS). They found no significant increase in the risk of suicide [risk ratio (RR) 1·13, 95% confidence interval (CI) 0·87-1·46], suicide attempt (RR 1·25, 95% CI 0·89-1·75) or suicidality (RR 1·26, 95% CI 0·97-1·64) among people with psoriasis. Singh et al. included 18 studies that were rated to be of medium quality to high quality according to the NOS. They found a pooled odds ratio (OR) of 2·05 (95% CI 1·54-2·74) for suicidal ideation among patients with psoriasis. For suicidal behaviours (combined attempted and completed suicides) a pooled OR of 1·26 (95% CI 1·13-1·40) was obtained, suggesting a higher risk of these behaviours in people with psoriasis. Subgroup analysis showed that patients with psoriasis were more likely to attempt suicide (OR 1·32, 95% CI 1·14-1·54) and complete suicide (OR 1·20, 95% CI 1·04-1·39) than those without psoriasis. CONCLUSIONS: Singh et al. concluded that patients with psoriasis have a significantly higher risk of suicidal ideation, suicide attempts and completed suicides, while Chi et al. concluded that the available, limited, very low-quality evidence does not support the notion of an association between psoriasis on the one hand, and suicide, suicidal ideation and suicide attempts on the other.

12-year changes in cardiovascular risk factors in people with major depressive or bipolar disorder: a prospective cohort analysis in Germany.

BACKGROUND: Major depressive disorder (MDD) and bipolar disorder are associated with certain cardiovascular risk factors (CVRFs), but it is unclear whether they are associated with unfavourable changes of clinically manifest CVRFs over time. METHODS: We used baseline and 12-year follow-up (n = 1887) data from the German Health Interview and Examination Survey 1998. Multivariable linear regression models assessed associations between lifetime CIDI-diagnosed mood disorders at baseline and continuous risk factor-related outcomes (blood pressure, HbA1c, LDL-C, HDL-C, triglycerides, BMI) at follow-up. RESULTS: We did not find consistent deterioration of CVRFs in persons with compared to persons without MDD. Analyses pointed to severity of mood disorder as an important correlate of long-term changes of comorbid hypertension: while a history of mild MDD was not associated with changes in CVRFs, moderate MDD was associated with lower blood pressure [systolic: ß = - 7.5 (CI - 13.2; - 1.9); diastolic: ß = - 4.5 (CI - 7.8; - 1.3)] and a history of bipolar disorder was associated with higher systolic blood pressure at follow-up (ß = 14.6; CI 4.9-24.4). Further, severe MDD was weakly associated with a higher BMI at follow-up [ß = 1.2 (CI 0.0; 2.4)]. These outcomes were not mediated by use of psychotropic medication and remained statistically significant after adjusting for the use of antihypertensive medication. CONCLUSION: Since most investigated parameters showed no associations, participants with a lifetime history of MDD in this cohort did not carry a specific risk for a worsening of pre-existing clinically manifest CVRFs. Our findings extend evidence of MDD severity and bipolar disorder as important correlates of long-term changes of arterial hypertension and obesity.

Prediabetes is associated with microalbuminuria, reduced kidney function and chronic kidney disease in the general population: The KORA (Cooperative Health Research in the Augsburg Region) F4-Study.

BACKGROUND AND AIMS: We investigated the associations of serum fasting (FG) and 2-h postload (2HG) glucose from an oral glucose tolerance test (OGTT), glycated hemoglobin (HbA1c), fasting insulin and the homeostasis model assessment-insulin resistance index (HOMA-IR) with urinary albumin-to-creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR). METHODS AND RESULTS: We performed cross-sectional analyses of 2713 subjects (1429 women; 52.7%) without known type 2 diabetes, aged 31-82 years, from the KORA (Cooperative Health Research in the Augsburg Region) F4-Study. FG, 2HG, HbA1c, fasting insulin, HOMA-IR and glucose tolerance categories were analyzed for association with ACR and eGFR in multivariable adjusted linear and median regression models, and with isolated microalbuminuria (i-MA), isolated reduced kidney function (i-RKF) and chronic kidney disease (CKD, defined as MA and/or RKF) in multivariable adjusted logistic regression models. Among the 2713 study participants, 28% revealed prediabetes (isolated impaired fasting glucose [i-IFG], isolated glucose tolerance [i-IGT] or both by American Diabetes Association definition), 4.2% had unknown type 2 diabetes, 6.5% had i-MA, 3.1% i-RKF and 10.9% CKD. In multivariable adjusted analysis, all continuous variables (FG, 2HG, HbA1c, fasting insulin and HOMA-IR) were associated with i-MA, i-RKF and CKD. The odds ratios (ORs) for i-MA and CKD were 1.54 (95% confidence interval: 1.02-2.33) and 1.58 (1.10-2.25) for individuals with i-IFG. Moreover, the OR for i-RKF was 2.57 (1.31-5.06) for individuals with IFG + IGT. CONCLUSION: Our findings suggest that prediabetes might have harmful effects on the kidney.

Prediabetes is associated with lower brain gray matter volume in the general population. The Study of Health in Pomerania (SHIP).

BACKGROUND AND AIMS: We investigated the associations of fasting (FG) and 2-h postload (2HG) plasma glucose from oral glucose tolerance test (OGTT) with gray (GMV) and white (WMV) matter volume. METHODS AND RESULTS: We analyzed data from 1330 subjects without known diabetes mellitus, aged 21 to 81, from the second cohort (SHIP-Trend-0) of the population-based Study of Health in Pomerania (SHIP). Following the OGTT, individuals were classified in five groups (according to the American Diabetes Association criteria): normal glucose tolerance (NGT), isolated impaired fasting glucose (i-IFG), isolated impaired glucose tolerance (i-IGT), combined IFG and IGT (IFG + IGT) and unknown type 2 diabetes mellitus (UDM). GMV and WMV were determined by magnetic resonance imaging. FG, 2HG and OGTT groups were associated with GMV and WMV by linear regression models adjusted for confounders. FG and 2HG were inversely associated with GMV. The adjusted mean GMV, when compared with the NGT group (584 ml [95% CI: 581 to 587]), was significantly lower in the groups i-IFG (578 ml [95% CI: 573 to 582]; p = 0.035) and UDM (562 ml [95% CI: 551 to 573]; p < 0.001), but not different in the i-IGT (586 ml [95% CI: 576 to 596]; p = 0.688) and IFG + IGT (579 ml [95% CI: 571 to 586]; p = 0.209) groups. There were no associations of FG, 2HG and OGTT parameters with WMV. CONCLUSION: Our findings suggest that elevated FG levels, even within the prediabetic range, might already have some harmful effects on GMV.

Do attitudes towards persons with mental illness worsen during the course of life? An age-period-cohort analysis.

OBJECTIVE: Cross-sectional studies frequently find higher age associated with negative attitudes towards persons with mental illness. We explore whether attitudes worsen over the life span, or follow a cohort pattern. METHOD: Using data from three identical population surveys in Germany from 1990, 2001 and 2011 (combined sample n = 7835), we performed age-period-cohort analyses determining the association of age, time period and birth-cohort with social distance from a person with either depression (n = 3910) or schizophrenia (n = 3925), using linear and nonlinear partial least squares regression models. RESULTS: Social distance increases with age, independent from cohort and period effects, cumulating to an increase of 2.4 (schizophrenia) and 2.3 (depression) on the 28 point social distance scale over the life span (youngest to oldest participant). We found a cohort effect in depression, but not schizophrenia, with decreasing social distance until 1970 and a slight increase in younger cohorts. Period effects were visible particularly in schizophrenia, with growing social distance over time. CONCLUSION: Considering demographic change and the vulnerability of older persons to severe outcomes of mental illness such as suicide, the observed increase of negative attitudes over the life span seems highly relevant. We discuss the role of conservatism and preferences for agreeable social contacts in older age.

Trends of barriers to eye care among adults with diagnosed diabetes in Germany, 1997-2012.

BACKGROUND AND AIMS: To study trends of barriers to receiving recommended eye care among subjects with diabetes aged 20-81 years in northeast Germany. METHODS AND RESULTS: We analyzed population-based data from two repeated cross-sectional surveys conducted in 1997-2001 and 2008-2012 (Ns of 4308 and 4402). Andersen's Behavioral Model of Health Services Utilization was used to identify individual-level demographic, financial and health-related barriers to annual eye-care utilization in subjects with a self-reported physician's diabetes and to examine population trends in these barriers. The prevalence of diabetes increased from 6.5% to 11.4%. The prevalence of annual eye-care utilization among persons with diabetes decreased from 69.4% to 56.0% (adjusted relative risk = 0.77, p < 0.001). The decline of eye care utilization over the past decade in eye-care use was more pronounced in groups at risk for diabetes-related complications (i.e., lower socio-economic status, >5 years since diagnosis of diabetes, poor glycemic control, obesity, smoking, lack of physical activity, co-existing diseases). We identified relevant predictors of missed annual eye-care use among diabetics. CONCLUSION: The increase of diabetes prevalence and downward trend of eye-care visits at the recommended level call for development, implementation and evaluation of continued efforts to improve access to eye specialists, particularly among those with poor diabetic control, co-existing diabetic complications, and comorbidities.

Long-term changes in body weight are associated with changes in blood pressure levels.

BACKGROUND AND AIMS: Hypertension and obesity are highly prevalent in Western societies. We investigated the associations of changes in body weight with changes in blood pressure and with incident hypertension, incident cardiovascular events, or incident normalization of blood pressure in patients who were hypertensive at baseline, over a 5-year period. METHODS AND RESULTS: Data of men and women aged 20-81 years of the Study of Health in Pomerania were used. Changes in body weight were related to changes in blood pressure by linear regression (n = 1875) adjusted for cofounders. Incident hypertension, incident cardiovascular events, or incident blood pressure normalization in patients who were hypertensive at baseline were investigated using Poisson regression (n = 3280) models. A change of 1 kg in body weight was positively associated with a change of 0.45 mm Hg (95% confidence interval (CI): 0.34-0.55 mm Hg) in systolic blood pressure, 0.32 mm Hg (95% CI: 0.25-0.38 mm Hg) in diastolic blood pressure, and 0.36 mm Hg (95% CI: 0.29-0.43 mm Hg) in mean arterial pressure (all p-values <0.001). A 5% weight loss reduced the relative risk (RR) of incident hypertension (RRs 0.84 (95% CI: 0.79-0.89)) and incident cardiovascular events (RRs 0.81 (95% CI: 0.68-0.98)) and increased the chance of incident blood pressure normalization in patients who were hypertensive at baseline by 15% (95% CI: 7-23%). CONCLUSIONS: Absolute and relative changes in body weight are positively associated with changes in blood pressure levels and also affect the risk of cardiovascular events.

[Integration of primary and secondary data in the Study of Health in Pomerania and description of clinical outcomes using stroke as an example]. / Die Integration von Primär- und Sekundärdaten in der Study of Health in Pomerania und die Beschreibung von klinischen Endpunkten am Beispiel Schlaganfall.

OBJECTIVE: This study describes (i) the procedure of obtaining patients' consent for secondary data usage, (ii) the complexity of integrating data from multiple sources, and (iii) the correspondence among patients' self-reports, physician reports, routine data, hospital discharge diagnosis, and cause-of-death coding regarding stroke. METHODS: Data from the first follow-up (N=3 186) of the population-based Study of Health in Pomerania (SHIP) were used. These data were combined with secondary data from the Greifswald University Hospital, the association of statutory health insurance physicians Mecklenburg-Western Pomerania, physician reports, and death certificates. RESULTS: Consent for using health-related information from all data sources in question was obtained from more than 90% of the SHIP participants. Follow-up data from at least one source were available for 2 747 (86%) participants. For 92 participants information about the occurrence of stroke was found in at least one data source. In 59 cases the event appeared in only one data source, in 24 cases the event was found in 2 sources, and for 9 participants 3 data sources reported on the event. CONCLUSION: Participants of a population-based cohort are highly willing to give consent for using their health-related information from secondary data sources. Yet, data integration is challenging due to considerable differences in data type, structure and coverage.

Sjögren's Disease and Oral Health: A Genetic Instrumental Variable Analysis.

Epidemiological studies have consistently shown that Sjögren's disease (SjD) increases the risk of dental caries. Despite similar evidence indicating an elevated risk of periodontitis, SjD remains a disputed risk factor for this disease. The risk of bias in observational research is a major impediment to confirming this link. Within an instrumental variable framework, genetic variants associated with a risk factor can be used to proxy its effect on an outcome while avoiding common sources of observational study bias. In this study, we leveraged an instrumental variable approach to investigate whether SjD affects the risk of caries and periodontitis. A total of 57 genetic variants strongly associated with SjD were identified from a genome-wide association study of 2,247 European descent cases and 332,115 controls. We tested for associations of these genetic instruments with caries (measured as the number of decayed, missing, and filled surfaces in 26,792 individuals) and periodontitis (17,353 clinical periodontitis cases and 28,210 European controls). Several sensitivity analyses were used to further validate the primary inverse variance weighted (IVW) estimate. IVW analysis revealed an adverse effect of SjD on caries (ß = 0.039, P = 6.3e-16) and periodontitis (odds ratio = 1.033, P = 2.3e-05). Sensitivity analyses, conducted to assess the robustness to potential violations of instrumental variable assumptions, further support these findings. Our results showed that SjD has a detrimental effect on caries and also suggest that SjD promotes periodontitis.

The Alcohol Harm Paradox in Periodontitis.

Individuals of lower socioeconomic position (SEP) experience a greater rate of alcohol-related harms, yet they consume equal or lower amounts of alcohol than higher-SEP individuals. This phenomenon, called the "alcohol harm paradox" (AHP), gained attention recently, and different mechanisms have been proposed to explain it. Since both SEP and alcohol have been suggested to be associated with periodontitis risk, we conducted a secondary analysis using data from the National Health and Nutrition Examination Survey 2011 to 2012 and 2013 to 2014 cycles, aiming to examine 1) whether the association between alcohol consumption and periodontitis is modified by SEP and 2) the extent to which the effect of SEP inequalities on periodontitis is mediated by and/or interacts with alcohol consumption. We set educational attainment as the main SEP proxy and tested the poverty income ratio in subsequent sensitivity analyses. Effect measure modification analysis was employed, considering heavy drinking as exposure, and causal mediation analysis based on the potential outcome's framework decomposed the effect of SEP on periodontitis in proportions attributable to mediation and interaction. Models were fitted using binary logistic regression and adjusted for sex, ethnicity, age, body mass index, smoking status, diabetes, binge drinking, and regular preventive dental visits. The analytical sample comprised 4,057 participants. After adjusting for covariates, less educated heavy drinkers presented 175% (odds ratio, 2.75; 95% confidence interval [CI], 2.04-3.72) higher odds of periodontitis than their counterparts, and super-additive associations were found (relative excess risk due to interaction: 1.35; 95% CI, 0.49-2.20). Additionally, -69.5% (95% CI, -122.1% to -16.8%) of the effects of education on periodontitis were attributable to interaction with heavy drinking, consistent with the AHP. No contribution was found for the mechanism of mediation. Heavy drinking disproportionately impacts the occurrence of periodontitis in lower-SEP individuals. Lower-SEP individuals seem to experience differential effects of heavy drinking on periodontitis.

Genome-wide association analysis of coffee drinking suggests association with CYP1A1/CYP1A2 and NRCAM.

Coffee consumption is a model for addictive behavior. We performed a meta-analysis of genome-wide association studies (GWASs) on coffee intake from 8 Caucasian cohorts (N=18 176) and sought replication of our top findings in a further 7929 individuals. We also performed a gene expression analysis treating different cell lines with caffeine. Genome-wide significant association was observed for two single-nucleotide polymorphisms (SNPs) in the 15q24 region. The two SNPs rs2470893 and rs2472297 (P-values=1.6 × 10(-11) and 2.7 × 10(-11)), which were also in strong linkage disequilibrium (r(2)=0.7) with each other, lie in the 23-kb long commonly shared 5' flanking region between CYP1A1 and CYP1A2 genes. CYP1A1 was found to be downregulated in lymphoblastoid cell lines treated with caffeine. CYP1A1 is known to metabolize polycyclic aromatic hydrocarbons, which are important constituents of coffee, whereas CYP1A2 is involved in the primary metabolism of caffeine. Significant evidence of association was also detected at rs382140 (P-value=3.9 × 10(-09)) near NRCAM-a gene implicated in vulnerability to addiction, and at another independent hit rs6495122 (P-value=7.1 × 10(-09))-an SNP associated with blood pressure-in the 15q24 region near the gene ULK3, in the meta-analysis of discovery and replication cohorts. Our results from GWASs and expression analysis also strongly implicate CAB39L in coffee drinking. Pathway analysis of differentially expressed genes revealed significantly enriched ubiquitin proteasome (P-value=2.2 × 10(-05)) and Parkinson's disease pathways (P-value=3.6 × 10(-05)).

[Multimorbidity and successful aging: the population-based KORA-Age study]. / Multimorbidität und erfolgreiches Altern: Ein Blick auf die Bevölkerung im Rahmen der KORA-Age-Studie.

BACKGROUND: The objective of the KORA-Age research consortium is to assess the determinants and consequences of multimorbidity in the elderly and to look into reasons for successful aging in the general public. PATIENTS AND METHODS: In the KORA-Age cohort study 9,197 persons were included who where born in the year 1943 or before and participants of previous KORA cohort studies conducted between 1984 and 2001 (KORA: Cooperative Health Research in the Region of Augsburg). The randomized intervention study KORINNA (Coronary infarct follow-up treatment in the elderly) tested a nurse-based case management program with 338 patients with myocardial infarct and included an evaluation in health economics. RESULTS: A total of 2,734 deaths were registered, 4,565 participants submitted a postal health status questionnaire and 4,127 participants were interviewed by telephone (response 76.2% and 68.9% respectively). A gender and age-stratified random sample of the cohort consisting of 1,079 persons took part in a physical examination (response 53.8%). CONCLUSION: The KORA-Age consortium was able to collect data in a large population-based sample and is contributing to the understanding of multimorbidity and successful aging.

Frequency and risk factors of post-intensive care syndrome components in a multicenter randomized controlled trial of German sepsis survivors.

BACKGROUND: Post-intensive care syndrome (PICS) is a combination of cognitive, psychiatric and physical impairments in survivors of critical illness and intensive care. There is little data on long-term co-occurrence of associated impairments. METHODS: Analysis of data from 289 sepsis survivors from a German multicenter RCT. Impairments associated with PICS (depression, PTSD, cognitive impairment, chronic pain, neuropathic symptoms, dysphagia) during 24 months follow-up are used to explore the frequency and risk factors of PICS components in three classification models. RESULTS: The majority of participants showed impairments in 2-3 of 6 domains during follow-up. The overall frequency of PICS according to the classification models ranged from 32.9% to 98.6%. In regression analyses, there were no significant effects in selected ICU-related exposures or covariates for PICS classification models. Regarding individual components, only higher age and longer duration of ICU treatment and mechanical ventilation showed significant positive associations with the occurrence of cognitive impairment during follow-up, as did male gender and higher age for dysphagia. CONCLUSIONS: Almost all study participants showed impairments associated with PICS in at least one domain. The proposed classification models for PICS appear to be too broad to identify specific risk factors beyond its individual components.

Prevalence of undiagnosed diabetes and impaired glucose regulation in 35-59-year-old individuals in Southern Germany: the KORA F4 Study.

AIMS: Limited data are available for European populations regarding the prevalence of diabetes and disturbed glucose metabolism in younger individuals. Our aim was to estimate the prevalence of diagnosed and undiagnosed diabetes, isolated impaired fasting glucose (i-IFG), isolated impaired glucose tolerance (i-IGT) and combined IFG/IGT in a population-based sample (n = 1653) from Southern Germany aged 35-59 years. METHODS: Oral glucose tolerance tests were carried out in all non-diabetic participants of the KORA F4 Study (2006-2008). Diabetes, IGT and IFG were defined according to the 1999 World Health Organization diagnostic criteria. The original IFG criteria (6.1-6.9 mmol/l) were used as recommended by the European Diabetes Epidemiology Group. RESULTS: The age-standardized prevalence was 2.2% for known diabetes, 2.0% for newly detected diabetes, 2.9% for i-IFG, 6.3% for i-IGT and 1.1% for combined IFG/IGT. About half of the cases with overt diabetes were undiagnosed in all age groups. The prevalence of i-IGT was approximately twice as high as that of i-IFG. The proportion of i-IGT varied between 3.2% (age group 35-44 years) and 11.8% (age group 55-59 years); the corresponding numbers for i-IFG were 1.1% and 5.9%. IFG/IGT was present in 1.2% of the total sample, and was most frequently found in the age group 55-59 years (2.4%). Overall, 16% of the study population had either diabetes or abnormalities of glucose metabolism. CONCLUSIONS: The study reveals for the first time a high prevalence of impaired glucose regulation in the younger and middle-aged German population. The detection of disturbed glucose metabolism or diabetes needs to be improved.

Prospective association of low serum total testosterone levels with health care utilization and costs in a population-based cohort of men.

Despite the burgeoning interest in the field of andrology, no studies have specifically addressed the impact of serum testosterone levels on healthcare utilization and costs. We analysed data from the population-based cohort Study of Health in Pomerania (SHIP), Germany, to assess the association of serum testosterone levels with self-reported health care utilization and costs at baseline and at 5 years follow up. Study sample comprised 2023 men at baseline, of whom 1530 men were repeatedly examined. Low and high serum testosterone levels, defined according to the age-specific 10th and 90th percentile, were compared with reference subjects with serum testosterone levels ≥10th -≤90th percentile. Two-part econometric models were applied adjusting for socio-economic and medical confounders. Cross-sectional models revealed higher numbers of outpatient visits and higher costs for both, men with low (+19.1 and +19.9%, respectively) and high serum testosterone levels (+25.3 and +30.2%, respectively), whereas number of inpatient days and costs were not associated with serum testosterone levels. Adjustment for age, educational level, income, waist circumference, smoking status, physical activity and alcohol consumption did not considerably alter the results. Longitudinal models revealed a significant association of low serum testosterone levels with increased number of follow-up outpatient visits (age-adjusted: +28.6%) and costs (+38.0%) only. Low and high serum testosterone levels were associated with increased short-term outpatient health care costs, whereas low serum testosterone levels appear to be predictive of long-term outpatient health care costs. Cost-effectiveness studies of available treatments are necessary to identify benefits for physicians, patients and health care system as a whole.

Microsurgical lymphatic vascular grafting and secondary liposuction: Results of combination treatment in secondary lymphedema.

Surgical treatment of lymphedema with liposuction typically requires subsequent compression therapy. Here we describe an approach where secondary arm lymphedemas are initially treated by autologous lymphatic grafting to bypass the axilla and restore lymphatic flow. In the presence of excess adipose tissue, liposuction is then performed in a second procedure. To assess outcomes, the authors evaluated 28 consecutive adult patients who had undergone secondary liposuction following lymphatic grafting. Arm volumes were measured prior to lymphatic grafting and after the secondary liposuction. The necessity for additional treatment by compression garment and manual lymphatic drainage was assessed prior to lymphatic grafting and after the secondary liposuction following the direct postoperative regimen. The mean arm volumes were reduced significantly (p<0.001) from a mean of 3417± 171 (SEM) cm3 prior to lymphatic grafting to 3020±125 cm3 after reconstruction of the lymphatic vascular system and finally to 2516±104 cm3 after the secondary liposuction (SLS). All 28 adult patients underwent continuous compression and manual lymph-drainage (MLD) prior to the reconstructive surgery. All 28 patients were evaluated regarding necessity of any additional therapy more than 6 months after SLS with a median follow up period of 37 months (range, 7-160 months). 18 of 28 patients did not require any supportive therapy beyond 6 months after SLS to maintain the results. Three patients continued to utilize manual lymphatic drainage, 4 used a combination of MLD and compression therapy and 3 used elastic compression therapy (one patient only while at work). These results indicate that microsurgical restoration of lymphatic outflow followed by SLS eliminates the need for additional treatment in more than two thirds of patients.

Area-level and individual correlates of active transportation among adults in Germany: A population-based multilevel study.

This study aimed at estimating the prevalence in adults of complying with the aerobic physical activity (PA) recommendation through transportation-related walking and cycling. Furthermore, potential determinants of transportation-related PA recommendation compliance were investigated. 10,872 men and 13,144 women aged 18 years or older participated in the cross-sectional 'German Health Update 2014/15 - EHIS' in Germany. Transportation-related walking and cycling were assessed using the European Health Interview Survey-Physical Activity Questionnaire. Three outcome indicators were constructed: walking, cycling, and total active transportation (≥600 metabolic equivalent, MET-min/week). Associations were analyzed using multilevel regression analysis. Forty-two percent of men and 39% of women achieved ≥600 MET-min/week with total active transportation. The corresponding percentages for walking were 27% and 28% and for cycling 17% and 13%, respectively. Higher population density, older age, lower income, higher work-related and leisure-time PA, not being obese, and better self-perceived health were positively associated with transportation-related walking and cycling and total active transportation among both men and women. The promotion of walking and cycling among inactive people has great potential to increase PA in the general adult population and to comply with PA recommendations. Several correlates of active transportation were identified which should be considered when planning public health policies and interventions.

Estimation of psycholeptic and psychoanaleptic medicine use in an adult general population sample using the Anatomical Therapeutic Chemical classification.

Little is known about psycholeptic and psychoanaleptic medicine (PM) use in the general population. This study presents prevalence data about PM use. The sample included 4310 individuals aged 20-79 from a general population health examination in a northern German area (participation proportion: 68.8%; Study of Health in Pomerania, SHIP). Medicines taken during the past seven days were assessed from the medicine packages or self-reports and classified according to the Anatomical Therapeutic Chemical (ATC) classification developed by the World Health Organization. In total, 6.3% of the sample reported PM intake, 8.7% of the women and 4.7% of the men. During the past 12 months prior to the health examination, 49.2% of the individuals with PM use consulted a general practitioner but not a neurologist or a psychiatrist. Among the study participants with PM use, 88.8% had one or more mental disorders during lifetime according to a screening questionnaire. It is concluded that considerable proportions of individuals with current PM use exist although lower than may be expected on the basis of the number of individuals with mental disorder in the general population.

[Experience with the s-GAP flap for autologous breast reconstruction]. / Der Stellenwert der s-GAP-Lappenplastik in der Brustrekonstruktion - Ein Erfahrungsbericht.

In breast reconstruction with autologous tissue the DIEP flap has become the gold standard in recent years. The superior gluteal artery perforator (s-GAP) flap is an alternative harvested from the buttock. We present our experience with the s-GAP flap and discuss its role in breast reconstruction. All s-GAP flaps performed for breast reconstruction in the Department of Plastic and Hand Surgery, Behandlungszentrum Vogtareuth from June 2002 until February 2007 were retrospectively analysed. Out of 59 flaps 4 flaps failed, the success rate was 94 %. Partial or fat necrosis occurred in 2 cases. The s-GAP flap served as a safe reconstructive alternative to the DIEP flap. Advantages of the s-GAP flap are reliable perforators, the safe vascular supply and the firm fat structure which facilitates the breast reconstruction. The donor site morbidity is minimal, the gluteal muscles stay intact and the scar is easy to hide in the underwear. Disadvantages are a demanding preparation with a prolonged operating time compared to the DIEP flap. The s-GAP flap is a reliable and safe option for autologeous breast reconstruction. It is the method of choice for staged bilateral breast reconstruction or if the DIEP flap is not available, particularly in the thin patient.
